Private Moment on Set: Nicole Wallace and Gabriel Guevara’s Intimate Laughs Spark Fan Frenzy Amid Romance Rumors

In the glittering yet unforgiving world of Hollywood’s international scene, where every glance and gesture can ignite a social media storm, actors Nicole Wallace and Gabriel Guevara have long been the unwitting stars of their own off-screen drama. Known for their sizzling chemistry as Noah and Nick in the Prime Video adaptation of Mercedes Ron’s Culpables saga—starting with My Fault (Culpa Mía) in 2023—the duo has captivated audiences with a forbidden romance that mirrors their characters’ turbulent love story. But recent whispers from the set of the trilogy’s third installment, Their Fault (Culpa Nuestra), have fans buzzing about a “private moment” that allegedly unfolded during filming: sources claim Wallace and Guevara were caught joking around and leaning in closer than usual for a full 20 minutes, oblivious to the crew around them. With Guevara publicly in a relationship with actress María de Nati, this supposed candid interaction has only fueled the obsession over their “secret connection,” turning what might have been a harmless bit of camaraderie into a full-blown scandal in the eyes of devoted shippers.

The incident, if reports are to be believed, occurred sometime in late 2024 during reshoots or additional scenes for Culpa Nuestra, which premiered to mixed reviews and heightened drama in October 2025. Eyewitness accounts—gleaned from anonymous crew members and leaked via fan forums and Threads discussions—paint a picture of unguarded joy amid the high-pressure environment of a film set. “They were in a corner, away from the main action, just cracking up over some inside joke from the script,” one source purportedly told a Spanish entertainment outlet. “Nicole was doubled over laughing, and Gabriel kept leaning in to whisper something that set her off again. It went on for at least 20 minutes—longer than a typical break. Everyone noticed, but no one wanted to interrupt.” The moment, captured in grainy, fan-circulated clips that have since gone viral on TikTok and X (formerly Twitter), shows the pair in animated conversation, their heads tilted toward each other in a way that screams intimacy. Wallace, with her signature wide smile and effortless poise, appears utterly relaxed, while Guevara’s hand occasionally brushes her arm—a touch that’s professional yet charged with the familiarity of co-stars who’ve shared steamy scenes.

Fans, ever the detectives of celebrity lore, have dissected these snippets with forensic precision. On X, hashtags like #Nicogab and #SecretCulpaConnection trended briefly last week, amassing over 500,000 views in 24 hours. One viral thread compiled “evidence” from the video: timestamps marking each lean-in, slow-motion replays of their shared laughs, and even lip-reading attempts suggesting playful banter about their characters’ endless drama. “This isn’t just friends joking—this is the spark we saw in My Fault bleeding into real life,” tweeted user @yanauzunova1, whose post featuring the clip garnered 275 likes and sparked a flurry of heart-eyes emojis. Replies poured in, with supporters gushing over the “undeniable chemistry” and skeptics warning against overstepping boundaries. “They’re adults having fun on set. Let them breathe,” countered another user, highlighting the double-edged sword of fan adoration.

What makes this “private moment” so intoxicating—and controversial—is the backdrop of Guevara’s confirmed relationship with María de Nati. The Spanish actress, best known for her roles in indie films and theater, went public with Guevara in early 2024, shortly after rumors of a Culpa Mía cast romance began swirling. Their coupling was a PR dream: two rising stars, often spotted at red-carpet events arm-in-arm, sharing subtle Instagram nods like vacation throwbacks and birthday shoutouts. De Nati, 29, has kept a low profile amid the frenzy, but sources close to the couple suggest she’s unfazed by the co-star speculation. “Gabriel’s always been clear: Nicole is a friend and colleague, nothing more,” an insider told FandomWire in a 2025 follow-up piece. Yet, the optics are tricky. Fans obsessed with the #Nicogab ship—estimated at over a million strong across platforms—have long projected their fantasies onto the pair, creating fanfics, edits, and conspiracy theories that blur the line between fiction and reality. The set moment, innocuous as it seems, has reignited debates about “shipping culture” and its toll on real relationships. “Knowing Gabriel has a girlfriend makes this feel like a betrayal, even if it’s not,” lamented one Reddit user in a r/CulpaMia thread, echoing sentiments from posts that racked up thousands of upvotes.

To understand the obsession, one must rewind to the trilogy’s origins. My Fault, released in June 2023, was a sleeper hit, adapting Ron’s Wattpad sensation about stepsiblings Noah (Wallace) and Nick (Guevara) entangled in a web of passion, betrayal, and family secrets. The film’s success—topping Netflix charts in over 50 countries—catapulted the then-21-year-old Wallace and 23-year-old Guevara into global stardom. Wallace, born in Madrid to an American mother and Spanish father, had been building a resume with roles in El Internado: Las Cumbres and Vertical Love. Her portrayal of the feisty, vulnerable Noah earned her a MTV Europe award nomination, and off-screen, she exuded a cool, Gen-Z vibe that resonated with young audiences. Guevara, son of Argentine actor Eduardo Guevara and Spanish actress Malène Mourreau, brought brooding intensity to Nick, drawing from his own experiences in Skam España and Hit.

Their on-screen rapport was electric from the jump. Promotional tours featured playful interviews where they’d finish each other’s sentences or reenact scenes with exaggerated flair. A 2023 YouTube clip of them playing “Who Knows Who Better?” has over 10 million views, filled with teasing glances and inside jokes that screamed “more than meets the eye.” Behind the scenes, leaks from My Fault‘s set showed unscripted moments: Guevara twirling Wallace during breaks, or her playfully shoving him after a flubbed line. “The way Nicole looks at him… it’s like she’s seeing Nick in real life,” one fan account posted, a sentiment echoed in countless edits set to Taylor Swift’s “Dress.” By Your Fault‘s December 2024 release, the hype was palpable, with billboards in Madrid featuring their embrace under the tagline “Love’s Fault Is Never Forgotten.”

But paradise cracked. Whispers of tension emerged in late 2023, tied to Guevara’s brief detention at the Venice Film Festival over unproven sexual assault allegations from his minor years in France—a cloud that briefly overshadowed his career but was dismissed by authorities. Around the same time, social media sleuths noted Wallace unfollowing Guevara on Instagram on November 1, 2023, coinciding with a cryptic Story of her lip-syncing to a breakup anthem. Fan theories exploded: Was it jealousy over Guevara’s party antics with ex Nuria? Body-shaming likes on posts mocking Wallace’s figure? Or simply the pressure of intense shipping? By Your Fault‘s premiere, the rift was public—Wallace walked off stage to avoid a joint photo, and they dodged eye contact on the carpet. Director Oriol Paulo reportedly mediated on-set squabbles, per IndieWire reports.

Enter Culpa Nuestra, filmed amid this frost. Production wrapped in early 2025, but reshoots in summer unearthed the “private moment.” Sources say the joking session was a rare thaw, perhaps fueled by script revisions demanding more emotional depth. “After all the drama, seeing them laugh like that felt like closure—or a spark,” a crew member shared anonymously on Threads. Fans latched on, flooding X with threads romanticizing it as proof of unresolved tension. One post, showing a clip of their hand-holding during a group scene (unscripted, per insiders), hit 44,000 likes: “They can’t stay away from each other.” Yet, darker posts accuse Guevara of disloyalty, citing his likes on anti-shipping comments like “keep dreaming” to Nicogab hopefuls. “He’s free to love who he wants, but this teases us,” vented @larossa1140952.

The girlfriend factor amplifies the intrigue. De Nati, Guevara’s steady since 2024, has been a pillar through his controversies, attending Culpa Tuya‘s afterparty solo while he promoted solo. Paparazzi shots of them cozy in Barcelona contrast sharply with the set buzz, leading to speculation: Is she the reason for past feuds, jealous of Wallace’s spotlight? A 2025 YouTube deep-dive, “Culpa Nuestra Exposed,” claims de Nati’s influence prompted Guevara to delete joint photos with Wallace, fueling the unfollow saga. Fans are divided—some defend the couple’s privacy (“Let Gabriel be happy with María!”), while shippers mourn the “what if,” editing montages of the set moment overlaid with Our Fault‘s soundtrack.

Wallace, now 23, has addressed the frenzy obliquely. In a November 2025 ELLE España interview, she quipped, “Chemistry on set is magic, but off-set, we’re just humans navigating life.” She’s since focused on solo projects, like a lead in Netflix’s upcoming thriller Echoes, signaling independence. Guevara, 24, echoed this in a GQ España sit-down: “Nicole’s talented; our bond is professional. Rumors are part of the game.” But actions speak louder—recent X posts show him liking fan art of Nick and Noah, keeping the door ajar for fantasy.

This obsession isn’t harmless. Shipping culture, while creative, has real fallout: Wallace reportedly sought therapy for anxiety from invasive DMs, per a 2024 Variety piece. The set moment, meant to humanize them, instead amplifies the pressure. As Culpa Nuestra streams to record views, one X user summed it up: “We love their love story—fictional or not. But let’s not ruin the real one.” In a world where private jokes become public property, Wallace and Guevara’s 20-minute escape reminds us: even stars crave unscripted moments. Whether it’s the rekindling of a friendship or the ghost of something more, the fans’ fixation ensures Nicogab endures—girlfriend or no.
